"TSATS": The Harbour Tug

9 posts in this topic

My entry of the "to sail the technic sea" contest is a floating vessel in the style of a Harbour tugboat. The feature of my tugboat is a Voith Schneider propulsion system. A classic propulsion system for ships works with a horizontal driveshaft and a propeller. The advantage of the vertical Voith Schneider propeller is, that it could adjust the boost of the propeller in all directions, without using a rudder.

The vessel can move sidewards and rotates in every radius which the captain wants. To get a little view on the maneuver abilitiys i made a short Video of my harbour tug

Two propellers in Voith Schneider style powered by twoPF-M motors with a gear ratio of 1:1.4
